________________
against the threat of death find themselves calm in otherwise frightening situation but hey also felt detached from what was happening the depersonalized state is one that mimics death, a person experience himself as emply, lifeless & unfamiliar. In a sense he creates psychologically the very situation that environmental circumstances threaten to impose. In so doing he escapes death for what has already happened can't happen again he cant die because he is already dead.
Russell Noyes suggest these contrasting strategies hyperalertness & depersonalization might be mediated by the same neural mechanism whose function is to help the organism to deal with danger by intensifying alertness while at the same time inhibiting potentially disorganized emotions. NDE tends to occur when the individual can do nothing directly to improve his or her chances of surviving the crisis. The sense of serenity is associated with an NDE serves to quiet the nervous system & conserve energy. It is probable that production of brain opiates endorphins is stimulated by these circumstances. In short when we perceive a dangerous situation we take practical action.
When we can & when we can't get it is time to seek refuge in a pleasantly tinged state of withdrawal.
It is also reasonable hypothesis report as well as experience serves a useful function text is created when individual is recovering we construct a story to describe & a/c for what happened..
NDE reports are texts not our direct experience we are limited in type of data available to us. NDE texts are subjected to analyses.
Morse proposed a fascinating but untested neural model for NDE. It is worth nothing that brain areas & functional networks to be mostly responsible for such experience. & also involved in imagination, creativity & fantasy Texts can vary with respect to their factual & imaginative content.
Karl Jensen psychiatrist supports neurophysiological arguments that NDEs are side effects of flood of brain chemicals he proposes that amino acid glutamate which is key chemical messenger in brain floods the brain in crisis times such as death threats becomes toxic Recent research suggest that the drug Ketamine can reproduce the characteristic of NDEs cause it prevents this toxicity. If brains natural chemicals acting like ketamine such as apiateen like endopsychosins do block the toxic glutamate flood they can provide the neurophysiological explanation for NDE.
